For best results It is important to follow proper mixing instructions when using salt with elevated trace elements, like FritzPRO RPM.

When Mixing RPM, it is best practice to use RO/DI water, quality checked by a TDS meter (TDS should be less than 10ppm, 0 is preferred). Fill Clean Mixing container (dedicated for aquarium saltwater) with desired amount of Saltwater to be prepared. We recommend using water between 70 – 75 degrees before adding RPM. Slowly add RPM into the RO/DI to avoid a sharp increase in temperature, and an over saturation of Salt. This helps to prevent precipitation of Calcium, Alkalinity and other trace elements. It is best practice to use a mixing pump and an air stone when mixing RPM. This will also help to avoid concentrated areas of material and precipitation. Using a properly calibrated refractometer, bring the salinity between 28-35 PPT (1.021-1.026 Specific Gravity). Once mixed to a clear solution, add a heater to the water to bring to the current temperature of your aquarium (78-80). Please allow 2 hours before doing a water change. If water does not mix clear please contact us for further mixing tips before doing a water change.

Best salt for the price point. Review by Murphys Aquatics @YouTube

Product Rating:

In the past I had used Red Sea pro, and Hw salt mixes. For the price Fritz mixes as fast as Red Sea and HW. The price point is friendly and won't sting your pockets. Alk mixes at about 9 to 9.4. Zero phosphate testing in a mixed batch. Dont buy into false claims or people pushing their lack husbandry on Fritz.. I Rate it as a 5.. (Posted on 7/11/2018)

Very Impressed with this salt!!!! Review by TJHOWELL

Product Rating:

(90 Gal SPS dominate) I used instant ocean reef crystals for the last 5 years.. not sure why because there salt DKH mixes high around 10 DKH to 11 most of the time. I keep my DKH around 8-9 which is what this salt mixes to. First salt mixed to 1.025 mixed DKH to 8.5, Magnesium to 1400, calcium to 410. This what I like to keep my tank levels around anyways through dosing pumps, so now my levels stay very stable whenever i do water changes now. 1/2 cup per gallon mixed pretty close to 1.025 . I mix it when the water temp is at 77 degrees and the water is crystal clear within 30min and ready for use. Amazing salt and I've already noticed my corals improving from a more stable water changes. I will be using this salt for this point forward. I recommend this salt to anyone that keeps there levels in this range. (Posted on 3/15/2018)

Used RS Coral Pro for a years and switch to RPM. Salt mixed clean and fast and gave me the dKH I was looking for. Coral/fish took to the change well and params are stable. Good switch and cheaper. (Posted on 2/20/2018)

Love This Salt Review by Sal

Product Rating:

Used Instant Ocean for 10 years, first six for my FOWLR and Reef Crystals for the last 4 in my 125g mixed reef...finally had enough of the residue left behind and sketchy parameters. Gave Fritz RPM a try and loved it. Perfect parameters every time. Easy and fast mixing, water is ready in 2 hours. Love this salt!!!! (Posted on 12/8/2017)
